Product cancellations are usually bad, but not if they are replaced with something better.

Intel's P1268 32nm development process is progressing better than expected. It is doing so well, in fact, that they are cancelling Havendale and Auburndale, the 45nm mainstream value versions of Nehalem. These were supposed to be the first mass produced chips with on die integrated graphics and an integrated memory controller.

Havendale was a dual core version of Lynnfield, itself the Core i5 mainstream version of the Nehalem Core i7. It would've used the same LGA-1156 socket as Lynnfield.

Auburndale was the mobile version of Havendale, but it had more in common with Clarksfield, the mobile variant of Lynnfield.

Having graphics on die saves motherboard manufacturers money because there is no longer a northbridge to buy and integrate. By lowering platform costs, Intel wants to bring Nehalem technology to a new market, at a price point it previously was not able to. This would also drive DDR3 adoption, something that DRAM manufacturers have been anticipating.

The original launch date for Havendale was towards the end of Q4, missing most of the crucial Christmas buying season. Auburndale would've been introduced in Q1 of 2010. This was to allow time for the production ramping of Lynnfield and Clarksfield into the mainstream market.

With 32nm development so advanced, Intel made the decision to pull in Clarkdale and Arrandale from the middle of 2010 to Q4 of 2009. They seem confident that they will be able to ramp in time to meet demand from the critical Christmas season.

Clarkdale is the 32nm successor to Havendale, built using two logic cores and a graphics core using Intel's "Multi-Chip Packaging". The logical cores are built on a 32nm process, but the integrated memory controller and graphics core are built on a 45nm process. It is capable of running four threads at once with a new generation of Hyper-Threading, promising increased efficiency. A server variant of Clarkdale is also to be introduced later in Q1 of 2010.

Arrandale is the mobile version of Clarkdale, also with integrated on die graphics. It will also allow switchable graphics within Windows 7 and Windows Vista, enabling the use of a higher performance GPU when plugged in. Both Clarkdale and Arrandale will use 5 series chipsets, exclusively with DDR3.
